How Much Fluoride Do Adults Need?
Your fluoride needs will depend on your oral health, but the American Dental Association (ADA) recommends a professional fluoride treatment at your dentist’s office every three, six, or 12 months.
According to the Mayo Clinic, they recommend adolescents and adults should get between 1.5 to 4 mg of fluoride daily.
The most effective way to introduce more fluoride into your mouth is to brush your teeth twice every day with fluoridated toothpaste. Depending on the brand and type of the toothpaste, one average use of fluoridated toothpaste can contain between one and three milligrams of fluoride.
You can also introduce more fluoride into your oral health through consumption of certain foods, such as taro root, yams, tea, milk, eggs, cassava, red meats, and fish, especially if it’s canned. For comparison, these foods generally contain less than 0.1 milligram of fluoride per serving.
